HOOP LUG AND CONNECTION.

To all whom "it may concern:

Be it known that 1, JOHN T. HOGAN, a citizen ol' the United States, a resident of the city and county of Denver, State of Colorado, temporarily residing at Los Angeles, in the county of Los Angeles and, State of California, have invented a new and useful Hoop Lug and Connection, of which the following is a specification.

The object of this invention is to provide superior means of very simple and inexpensive construction for connecting the ends 01' the band of adjustable hoops on tanks and other circular vessels, whereby the force applied to tighten the band will operate more fully to draw the ends of the band together, than with the construction heretofore em ployed.

The invention includes the improved means for connecting said ends of the band, and also the improved means for drawing said ends toward each other.

A further object of the invention is to pro vide superior means whereby the connecting appliance may be attached to the ends of the hoop bands in the most convenient and ready manner without any liability of slippage.

Another object is to make provision whereby the band and the parts directly connected thereto in the present application of this novel connecting appliance will not interfere with the operation of the parts by which the tension is applied to the band.

The accompanying drawings illustrate the invention.

Figure 1 is a view of the invention. as applied in a hoop on a tank, fragments of the hoop and tank being shown. Fig. 2 is a longitudinal section of parts shown in Fig. 1.

1, 1 designate the ends of a band of the usual character which forms the main encircling body of the hoop.

2, 2 designate two lugs each of which comand an eye 4. The perforation 5 of the eye extends longitudinally, and the recess 6 extends be tween the slot 7 and the end of the base opposite the eye, and on the opposite side of the base from which the eye projects.

8 designates strengthening ribs at the sides of the base.

9 designates a recess adjacent the eye 4 to accommodate the tightening nut 10.

nection the terminals of which extendv through the eyes 4, 4.

The nuts 10, 10 are screwed onto the ends of the flexible connection to force the lugs toward each other. The ends of the band are respectively bent onto the lugs by inserting each end through the slot of its lugs and bending it about the bar 12 of its lug, the recess between the slot and the end of the lug accommodating the inbent portion of the band. The inbcnt portion of the band may be of any required length so that in practical operation the workman may sim ly insert the end of the band through the s ot such a distance as to bring the eyes of the lugs at an appropriate distance apart when the band is brought to proper position on the tank or other vessel to be hooped.

One end of the flexible connection may at the outset be secured. to one of the lugs, the

other end of the flexible connection being left free and without its nut so that it may be inserted through the eye of the other lug when the band has been brought into position on the tank. The workman may hamnier the band flat at the bent places, and w en the band. is in proper position on the tank, may insert the free end of the flexible connection through the eye that is to receive the same the nut being brought into posi tion in its recess, and turned to screw it onto the free end of the flexible connection. Then one or both of the nuts may be tightened as required to draw the lugs toward each other, thereby tightening the hoop. The flexible connection may be made of two parts (1/, l), hinged. or' jointed together in the middle, as shown in Figs. 1 and 2, or it may be constructed in some other fashion but flexible in the middle. When the nuts are tightened, the force is thus exerted. in a direction most effective to draw the ends of the band together and entirely without the opposing forces that operate when a straight or rigid bolt is used such a bolt applying the force used in a difl'erent tangent from the direction of the hoop, and the force so exerted is opposed by the transverse pull of the tightening hoop on the middle of the straight bolt heretofore employed.

The orifices 5 of the eyes are of consider able length, and the *portions of the flexible connection which extend through said eyes are referably rigid so that they will move free y axially in the perforation. In the preferred form, the flexible connection is formed of a plurality of members and is provided between the rigid shanks with a joint which is in the middle of the connection. In this way the tendency to bend the members in or at the margin of the orifice of the eye is minimized.

It is evident that Various means may be employed for fastening either end of the flexible connection, the other end being provided with the adjustable fastening means as the nut, but it is best to provide both ends with nuts as shown.

I claim Means for connecting the ends of a hoop, the same comprising two lugs each having a transverse slot at one end through which the end of a hoop can be inserted and doubled under and thus pressed against the tank or cylinder, the other end of each lug having a protuberance rovided with a longitudinal eye, two threac ed eye-bolts the eyes of which are interlocked and the shanks of which extend through the longitudinal eyes respectively, and nuts screwed on the bolts to draw the lugs toward the interlocked eyes.

In testimony whereof, I have hereunto set my hand at Los 'Angeles, California, this 19th day of June, 1908.

JOHN HOGAN.
